A MEASURE OF DIJKSTRA'S SCIENTIFIC INFLUENCE
On 11 January 1987, Dijkstra wrote his one thousandth EWD. At the end of that EWD, Dijkstra made an important request:
Would everybody — and this time I really mean everybody — who sees this text be so kind as to inform me that he or she has seen it? A postcard stating name (and affiliation) suffices.
Dijkstra subsequently received several postcards and put them in a separate map which I now have in my possession. During the coming months, I will make the names of the postcards' senders publically available below. They are historically valuable because they help us grasp the extent of Dijkstra's influence.
